It has been confirmed on X10 blog that the X10 will get the official 2.3.3 upgrade. However, the X10 mini/pro and X8 users wont....Here's what the SE Blogs had to say:

Update on Xperia™ X10

I have been working with this blog for almost 1 ½ years. After lots of interaction and discussion, by far the most intense discussions lately were around XperiaTM X10 Android upgrades. We earlier stated that we did not have plans for further upgrade of the XperiaTM X10 beyond Android 2.1 Éclair, which was correct at the time.

However, I am happy to inform you that this has changed. We plan to bring an upgrade to Android Gingerbread for the XperiaTM X10 to generic trade kits end Q2 / early Q3 this year. We have heard your requests all along but until today have not been able to confirm this. The great work on our 2011 products XperiaTM PLAY, XperiaTM arc and XperiaTM neo actually has enabled us to start the work in a special project bringing Gingerbread to the XperiaTM X10.

I believe this is good news to many of you out there and I am sure you have many questions around this. I’ve tried to list answers to the ones that came to my mind below. More details will come closer to launch but let me know in the comments section if I missed any questions. I’ll do my very best to find out and follow-up!

Why are you doing this upgrade?

We have listened to our consumers. In addition, the development of the software for our new 2011 range of Xperia phones gave us a solution that made it possible to deliver Gingerbread on XperiaTM X10.

When will the upgrade be available for me?

The roll-out is planned to start end Q2/early Q3 this year. Today, XperiaTM X10 is available in the market both in generic trade version and in versions customized for operators. Due to the resources available in this special project, we will focus on delivering trade versions of the software. Regarding possible customized operators kit we will have to get back with more information on this at a later stage. But we want to be very clear already at this stage on the fact that some of you may not get this upgrade.

What are the components of this upgrade and what are the major differences from the 2.1 version of XperiaTM X10?

In short, we plan to bring similar software and functionality to XperiaTM X10 as we have in our new 2011 Xperia smartphones. Our ambition is to provide the majority of functionality of the Gingerbread platform, as well as the Sony Ericsson specific User Experience and features. The final scope of the software is still a work in progress. We will get back with more details closer to launch in end Q2 / early Q3 this year.

Will any functionality from the previous software version disappear by doing this upgrade?

Yes – the work is still ongoing so details will be communicated closer to launch but these are the current expected limitations:

The current plan is that the XperiaTM X10 will get the Android standard Camera user interface and therefore features like e.g. face recognition, smile shutter etc will be lost.

Moxier is replaced by the gingerbread native EAS functionality.

Mediascape is being replaced by the media experience widgets and music player included in our new 2011 products.

DRM keys for protected content on your phone will be lost in the upgrade process.

The Sony Ericsson Backup and Restore client is not supported in the Gingerbread version and will therefore be lost.

Support for bi-directional languages will be reduced compared to the latest version of the 2.1 version of the XperiaTM X10.

What are the major differences between 2.3 on XperiaTM X10 and 2.3 on your 2011 range, for example Xperia arc?

In short, the intention is that the Xperia X10 will receive similar software and functionality that we have in our new 2011 Xperia smartphones. The current ambition is to provide the majority of functionality of the Gingerbread platform, as well as the Sony Ericsson specific UI and features that are not restricted by hardware limitations (for example no HDMI out). The final scope of the software is still work in progress but we are working to minimize the differences. We will get back with more details closer to launch.

Whilst Xperia X10 owners are rejoicing on the news about Android Gingerbread heading to the headset, unfortunately it is not good news for the smaller Xperia models. Sony Ericsson has confirmed that as they need to “prioritise” their resources and thus there are no current plans for the X10 mini, X10 mini pro and X8 to receive the update. What we do know with SE is that they always seem to change their mind, so if you’re being optimistic maybe we will see it at some point down the road after all.
